Man-of-the-match Bruno Fernandes, Anthony Martial and Mason Greenwood fired Manchester United to an impressive victory against relegation-threatened Watford.
After falling to their most chastening loss of the season at Vicarage Road two months ago, Ole Gunnar Solskjaer's men exacted revenge in style, as they followed up a victory at Chelsea a week ago.
Fernandes' nonchalant penalty gave the hosts a half-time lead that Martial and Greenwood superbly added to in a 3-0 victory that moves United up to fifth, just three points behind Frank Lampard's side in fourth.
United paid tribute to the late Harry Gregg, the hero of the Munich air disaster, before kick-off at Old Trafford.
January signing Fernandes calmed the nerves in a superb individual display, tucking away the penalty he won, before Martial showing similar coolness, when clipping the ball past former United goalkeeper Ben Foster in the second half.
Troy Deeney had an equaliser ruled out minutes earlier by the video assistant, but Greenwood, still only 18, hit a thundering strike off the underside of the bar to complete United's victory.
Wolverhampton Wanderers are two points behind United in eighth, after their 3-0 win against bottom side Norwich City, with Diogo Jota scoring a first-half double and Raul Jimenez turning in the third.
Arsenal moved to ninth following a thrilling 3-2 win at home to Everton, leaving the 'Gunners' just three-points from a European spot.
